HI there, I am using the CYBLE-012011-00 and I am having trouble programming my BLE to stop scanning even after following the required steps. Please see below my code. It is acting as an observer to an advertiser.

void StackEventHandler(uint32 event, void* eventParam)

{

    /*local variables*/

   CYBLE_GAPC_ADV_REPORT_T advReport;

    switch(event)

    {

        case CYBLE_EVT_STACK_ON:    /*BLE stack ON*/

                /*Start Scanning*/

                if(CYBLE_ERROR_OK==CyBle_GapcStartScan(CYBLE_SCANNING_FAST))

                {

                    printf("Started to Scan\r\n");

                }

            break;

        case CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT:

                advReport=*(CYBLE_GAPC_ADV_REPORT_T *)eventParam;

            break;

         case  CYBLE_EVT_GAPC_SCAN_START_STOP:

                UART_H2B_UartPutString("\r\nCYBLE_EVT_GAPC_SCAN_START_STOP\r\n");

            break;

        default:

            break;

    }

}

/********************************************************************************************************

* Function Name : BLE();

********************************************************************************************************/

int BLE(void)

{

    CYBLE_API_RESULT_T apiResult;

    CYBLE_STATE_T CYBLE_State;

    CyGlobalIntEnable;

    Connection_end = 0;

    while(Connection_end == 0)

    {

        apiResult = CyBle_Start(StackEventHandler);

        CyBle_GapcStartScan(CYBLE_SCANNING_FAST);

        CyBle_ProcessEvents();

    }

    while(CYBLE_State != CYBLE_STATE_DISCONNECTED)

    {

        CyBle_GapcStopScan();

        CyBle_ProcessEvents();

        CYBLE_State = CyBle_GetState();

     }

}

Essentially it remains in CYBLE_State = CYBLE_SCANNING

1) Has anyone else had a similar problem and if so is there a solution?

2) I can use CYBLE_SetState() to get to CYBLE_State = CYBLE_STATE_DISCONNECTED. However when I go into deepsleep I am waking up with no other interrupts, So I suspect it may still not be actually functioning correctly.

Any help would be greatly appreciated!

Hi there,

I'm trying to find a suitable BLE solution for an upcoming product. We're looking for a BLE Controller that we can integrate with BlueZ on a Linux system. In other words we're looking for access to the HCI layer of the bluetooth stack. We're also hoping to find one that is available as a module, so we don't have to implement the RF chain ourselves.

I've seen a few posts on the community forums about using HCI mode for testing and the like, but I haven't found much documentation from Cypress on which software stacks can break out this layer. I've also seen this list of Cypress' Bluetooth qualifications which suggests that you can pick and choose which parts of the stack you can include in your firmware build.

Can you provide some more information? If we want a pre-qualified BLE controller available as a pre-certified module for our product, which chipsets are suitable, and where should I be looking to understand the software stack? To further complicate things we're hoping to find a solution that will enable us to update the firmware stack in the future to support BLE Mesh.

Thanks,

Tom

Dear

I have a question about CapSense Slider.

I am going to evaluate PSoC4S.
(using evaluation board: CY8CKIT-145-40XX)

I'm checking a worst case scenario test.
In particular, when move very slowly finger on sensor, whether it can be detect.
(For example, take 10 seconds to move to the next electrode B from a electrode A)

Such a case, the raw count always rise within electrode B becomes slow, because diff count is less than threshold.
Therefore, baseline within electrode B keeps track an compensates for the raw count.
When my finger complete move to electrode B, CapSense cannot detect my finger.(because diff count is less than threshold.)

In such a case, I want to detect my finger on electrode B.
what would be a good way to do it?
Probably, about speed to finger slide, exist a restriction?
